Transcript
Topical antifungals are medications used to treat cutaneous fungal infections, which are conditions that affect the skin, hair, and nails, and can be caused by a variety of fungi, such as Candida albicans or dermatophytes.
The most commonly used topical antifungals include nystatin, tavaborole, ciclopirox, and azoles like ketoconazole, miconazole, econazole, and efinaconazole. These medications are applied topically on the affected skin, in the form of ointments, creams, gels, or foams.
Once administered, topical antifungals work by disrupting and damaging the fungal cell membranes, ultimately resulting in a fungistatic action, meaning that they stop fungal growth, or a fungicidal action, meaning they kill the fungi.
As far as side effects go, topical administration of antifungals can cause the development of a skin rash, as well as itching, and burning of the skin area.
Additionally, some clients may present with serious hypersensitivity reactions, such as Stevens-Johnson syndrome. Fortunately, there are no major contraindications for the use of topical antifungals.
Alright, when caring for a client that is prescribed a topical antifungal medication like ketoconazole, first assess the affected skin area, making note of the presence of moist, red patches, papules, pustules, and discharge, as well as itching, burning, and pain. Then, review recent laboratory test results, including results from skin scrapings.
Next, be sure to teach your client how the prescribed medication can help treat their cutaneous fungal infection. Remind them that the medication is for topical use only, and not for ophthalmic, oral, or vaginal use.
Summary
Topical antifungals are medications that are applied directly to the skin or nails to treat fungal infections. They work by killing or stopping the growth of fungi that cause infections.
Topical antifungal medications are available in various forms, including creams, lotions, gels, sprays, and powders. Commonly used topical antifungals include nystatin, tavaborole, ciclopirox, and azoles like ketoconazole, miconazole, econazole, and efinaconazole.
Topical antifungal medications are used to treat different skin infections including tinea corporis, tinea pedis, and pityriasis versicolor.Topical antifungals are generally safe and well-tolerated, and side effects are uncommon. However, some people may experience mild to moderate side effects, including skin irritation, allergic reactions, and discoloration of skin, hair or nails.
